PLEASE HELP! What is the value of x?

Mathematics
2 answers:
Minchanka [31]3 years ago

The two sides are congruent so the value of x can be found with the equation 5x+10=40.

5x+10-10=40-10

5x=30

5x/5=30/5

x=6

It is a rectangle so its opposite sides are congruent. Because they are congruent we can set them equal to each other and solve for x.

40 = 5x + 10
30 = 5x 
6 = x

So the value of x is 6.

What is the value of x?
Luden [163]

This is an isosceles triangle because the picture shows it has two equal sides. Isosceles triangles have two equal angles.

The sum of all the angles of a triangle = 180º.

We can use this equation to solve for x:

2x + 54 = 180.

     - 54    -54     Subtract 54 from both sides.

2x = 126

/ 2     /2  Divide 2 from both sides to isolate x.

x = 63º

Let's check! 63 + 63 + 54 = 180? YUP!
